L The Schedule referred to in these Lettem f'atent and making par: ofthe same provements in Chairs; and do hereby declare that the followingis a full, clear, and exact description thereof, reference licnighad to'the accompanying drawing inaking a part ot'this specification, in whiehF1gi11*e 1 is a side elevation ot'a chair, provided with niyimproredlegs, andp, o

Figure 2 isa likeview of a stool fora swirel-clniir, showing amodification in the form of the legs attheir pomts of attachment to theseat.

Letters of like name and lii'nd'refer to like parts in each of thefigures. 4 l H The object of my inrentic-nis to provide chair-legs thatshall be sntiiciently elastic to insure a hearing for each upon thefloor, regardless of-a-nyordinary nuevenness of thesan'ie and a p I 7 Itconsists principally in a chair-leg constructed of metal rods or wire,and. provided with two or more a spiral cods,hav1ngtheir axis placed at,or, near a'right radially from the center of the with the legs betweentheir lower ends and the. seat,

1 asis hereinafter shown. i

In the annexed drawing-- p :A represents the seat of anonlinarychair,which rests upon and is supported hy the legs 13, constructed of; WW6 mthe following manner ,Thewire is bent nearly together-at its center, in

the form shown at b, after which each half is bent spirally one and onehali' times, so as to form two cells, 0, the axes of whichareeoincident, while their innerfiicesare parallel with and at a shortdistance, from-each other. From the coils O the wires extend upwardmidway to tlieehair-seat, where, by a single turn of each, two othercoils, D, are formed upon the oppositeor onterside of the leg from thefirst coil 0.

the spiral fcoils, any degreeof'rigidity" A thirdset of coils, E, isformed upon the inner side of the leg near the seat A, alter which theends of the wire pass directly upward into the same, as in he. 2, or'arecrossed and enter said seat diagonallgas shown in fig. 1'.

Passing horizontally around the legs B, and through the central coilsI), is a metal ring or hoop, 1!, which confines said legs at theircenter, and prevents, *attliat 7 point, any radial movement of the same.

7 As thus constructed and applied, downward pressure uponth'e seat willcause the lower ends of the legs to spring outward, and their upperends-to spring slightly inward, until each has a firm bearinguponthefloor,

after which anyincreasc of saidpressnre n 1 illciuse;

snidlegs to further change their original sl apc,g,u til such pressureis'e'qualized by their increasedgteusioif; iiinheroi; lastieity Byvarying theisize of the wire and'th may he ohtaiued-for the legs, so asto adapt them to: the weight to he sustained.

The advantages possessed by this construction of the legs are, thatbeing elastic, each leg is sure to iiud a bearing upon the floor, whilethe same property rend-e crs the chair more easy and comfortable to theoccnpant. 1 i r 1 Having thus fully set forth the nature and merits ofmy invention, Q What I claim as new, is-- X chair-leg constructed ofparallel metal rods or;- wire, each provided with two or more spiralcoils, sub-f stantiall y as shown and for the purpose specified.

I Also, in combination with chair-legs constrneted ofwire, as described,a circular metal ring or hoop for confining the same in positionradially, substantially as and for the purpose set forth.

In testimony that I claim theforegoing, I "have hereunto'set my handthisfZSth day ot'Jline, 1870. I i bANll llrEj'll lAL;
